How do you pick a good site for a Sigma Rain Gauge?
Site considerations for successful installation of a Sigma Rain Gauge
To get accurate results consider the following issues:
- Beware of objects that might block the rain from falling into the rain gauge
- Trees or shrubs
- Due to wind, these objects need to be a good distance away from the rain gauge. The taller the object, the farther away.
- The rain gauge must sit on a level surface
- The rain gauge base can be adjusted to make sure it is flat.
- However, the adjustment can only adjust for small deviations. Pick a surface that is nearly flat.
- Make sure the rain gauge is safe from high winds.
- Make sure to attach the Rain Gauge to a solid, heavy base. A cement block approximately 12” X 12” X 1” works well.
- Not in a location exposed to very high winds.
- Make sure the rain gauge is in a location free from access by unauthorized persons. Vandalism is a real problem.
- The following can plug the rain gauge funnel, making it read “no rain:”
- Pollen and leaves from trees and bushes
- Grass clipping from mowers.
- Birds droppings from birds sitting on the rain gauge.
- Dust and dirt.
- These are often hard to predict (birds, for example). Watch the data and move the rain gauge if there is an issue.
